Please show all working out and checking that it is the correct answer using any methods. Thanks in advance.

Suppose we have a non-uniform beam that is 2.82 metres long has a flexural rigidity of 12831+250x331039800Nm2. Find the deflection of the beam in millimetres if the beam is under a uniform distributed load of 71mN and is supported with a fixed support on the left end, and a simple support on the right end. Fill out the table below with your answers
